The brake on/off is controlled via signal 3.15 BRAKE COMMAND. The source for the brake
supervision is selected by parameter 35.02 BRAKE ACKNOWL.
The brake control hardware and wirings need to be done by the user.
• Brake on/off control through selected relay/digital output.
• Brake supervision through selected digital input.
• Emergency brake switch in the brake control circuit.
• Brake on/off control through relay output (i.e. parameter 12.12 RO1 OUT PTR is set to P.03.15 =
3.15 BRAKE COMMAND).
• Brake supervision through digital input DI5 (i.e. parameter 35.02 BRAKE ACKNOWL is set to
P.02.01.04 = 2.01 DI STATUS bit 4)
